Final answer:
Drinking sea water should be avoided because it is hypertonic and can lead to dehydration and potentially death.
Step-by-step explanation:
Drinking sea water should be avoided because it has a higher osmotic pressure than most bodily fluids. Sea water is hypertonic, meaning it has a higher solute concentration than our cells. When we drink sea water, osmosis pulls water out of our cells to dilute the salt, leading to dehydration and potentially death. Our bodies are better equipped to handle hypotonic solutions, where the solute concentration is lower.
